Claims.

This invention relates to improvements in breast-strap fasteners for infant chairs of the type having arm-rests supported in connection with a seat.

Generally breast-straps are secured to the arm-rests of infant chairs by means of snap fas.. teners on the ends of the breast-straps that are connected with screw-eyes driven into the armrests. Frequently, such connections are insecure because of the tendency of the screw-eyes to become loose, turn from one position to another, or pull out of place, thus permitting the occupant to fall from the chair.

An object of this invention is to afford an attachment for securing a breast-strap to the armrests of chairs in such manner that the attachment has separate connections with the arm-rest and the support therefor, thus to circumvent turning or dislodgment of the attachment.

Another object of the invention is to afford a breast-strap fastener for an arm-chair provided with means for securing said fastener individually to the arm-rest and the support therefor, thus to hold the fastener in a definite position on the arm-rest.

Other objects and advantages of the invention appear in the following description.

An illustrative embodiment of the invention is shown in the accompanying drawing, in which- Fig. 1 is a view Of an ordinary infants armchair of a well-known type, equipped with the invention, the view being a longitudinal section;

Fig. 2 is a fragmentary front elevationa view projected from Fig. l;

Fig. 3 is an enlarged fragmentary top plan view of an arm-rest to which the invention is attached;

Fig. 4 is a side elevational view of'the structure shown in Fig.3; and

Fig. 5 is a perspective view of a fastener embodying the invention.

An illustrative embodiment of the invention preferably consists of a fixture formed of wire shaped to provide an elongated loop I for the reception therethrough of a breast-strap 2, a radially extending threaded end portion 3 contiguous with one terminal of the loop, and a laterally extending portion 4 contiguous with the other loop terminal having an eye 5 formed at its outer end constituting an anchor.

In Figs. 1 and 2 is shown a folding arm chair to which the invention is applicable, the chair consisting of a seat 6, folding back-rest I pivoted on the seat, arm-rests 8 connected at their rear ends to the back-rest by pivots 9, and supported at their forward end portions by links In that are connected at their opposite ends respectively with said arms and seat by pivots H and I2.

The breast-strap fixtures are secured to the arms of the chair by first screwing the threaded portions 3 directly into the arms, then placing the eyes 5 of the anchors correspondingly between the arms and the upper ends of the links Ill, and finally driving the pivot screws ll through the perforated upper end portions of the links In and the interposed anchor eyes 5 into the arms 8. In this manner the fixture is supported by its threaded portion which is secured in the arm-rest and also by its anchor which is secured in connection with the arm-rest andthe supporting link by the pivot screw therefor, so the fixture is held in a definite selected position on the arm-rest and is thus prevented from turning upon the axis of the threaded portion or becoming accidentally detached from the chair. The anchor eye being disposed on the pivot screw between the arm-rest and the link prevents relative movement of the fixture with respect to the arm-rest while permitting the link to turn upon the pivot screw when folding or unfolding of the chair.

Variations from the particular construction above disclosed may readily be made by exercise of engineering skill without departure from the spirit or scope of the invention, and the following claims are intended to be inclusive of such variations.

What I claim is:

1. A fixture for attachment of a breast-strap to the arm-rest of a chair where the ar -rest has a supporting link secured thereto by a pivot rscrew, said fixture being formed of wire shaped to provide a loop for reception therethrough of a breast-strap, a radially extending threaded portion contiguous with one terminalof said loop, and a laterally extending portion contiguous with the other loop terminal provided at its outer end with an eye constituting an anchor, the arrangement being such that when said threaded extension is screwed into the arm-rest and said anchor is secured on the pivot screw, said fixture is held in a definite selected position on the arm-rest.

2. A fixture for securing a breast-strap to the arm-rest of a chair where the arm-rest has a supporting link and a pivotal connection for said link, said fixture having a loop for attachment of a breast-strap, an extending threaded portion contiguous with one terminal of the loop adapted to be screwed into said arm-rest and a laterally turning movement of said fixture relative to said 1 an anchor member extending between said support and arm-rest, and means connecting said support, anchor and arm-rest together wherefore to hold said loop in a definite selected position on the arm-rest.

5. A fixture for attachment of a breast-strap to the arm-rest of a chair, said fixture having a loop adapted for connection of a breast-strap thereto, provided witha projecting member adapted for threaded engagement in said armrest, and an angularly extending member seowed to said arm-rest at a point thereon spaced arm-rest. v 1

4. m an arm chair structure having an armrest and a support therefon'a fixture having "a" loop for attachment of a, breast-strap provided with an extension threaded in said arm-rest and apart-from the other member wherefore to prevent turning of said loop from a definite selected "position said arm-rest.
